A boy reaches his school 1.4km away in 1hr 40mins at what speed does he travels?
speed = distance/time, so
1.4km/1.667hr = 0.84 km/hr
or, using fractions,
(7/5)km/(5/3)hr = 21/25 km/hr
Well, if we do some math, we can figure out the speed at which the boy traveled. So, 1 hour and 40 minutes is the same as 100 minutes. And since he traveled 1.4 kilometers in that time, we can calculate his speed by dividing the distance by the time. So, if we divide 1.4 kilometers by 100 minutes, we get... um, well, let's just say it's not the fastest speed in the world. I mean, even a snail could probably beat that speed. But hey, at least the boy made it to school! That's what counts, right?
To find the speed at which the boy traveled, we can use the formula:
Speed = Distance / Time
Given that the distance is 1.4 km and the time is 1 hour 40 minutes, we need to convert the time to hours.
1 hour 40 minutes = 1 + (40/60) hours = 1.67 hours
Now we can calculate the speed:
Speed = 1.4 km / 1.67 hours
Speed ≈ 0.8383 km/h (rounded to four decimal places)
Therefore, the boy traveled at a speed of approximately 0.8383 km/h.
To determine the speed at which the boy travels, we need to use the formula:
Speed = Distance / Time
Given:
Distance = 1.4 km
Time = 1 hour 40 minutes
First, we need to convert the time into hours. Since there are 60 minutes in an hour, 1 hour 40 minutes is equivalent to 1.67 hours.
Now we can substitute the values into the formula:
Speed = 1.4 km / 1.67 hours
Calculating this, we get:
Speed ≈ 0.84 km/h
Therefore, the boy travels at a speed of approximately 0.84 kilometers per hour.
