Sue bikes at a rate of 15 miles for 1.25 hours. If she takes 0.75 hours to bike the same distance next week, how fast will she bike then?
PLZ HELPPPPPPPP!!!!!!!!! A S A P
distance = speed * time, so
0.75x = 1.25*15
I got 20 mph.
To find out how fast Sue will bike next week, we can use the formula for speed: speed = distance / time.
First, we need to calculate the distance Sue biked this week. We know she biked at a rate of 15 miles for 1.25 hours, so the distance is given by: distance = rate * time = 15 miles/hour * 1.25 hours = 18.75 miles.
Next, we can use the distance Sue biked this week to find her speed next week. Since the distance remains the same (18.75 miles), but the time decreases to 0.75 hours, we can use the formula again: speed = distance / time = 18.75 miles / 0.75 hours = 25 miles/hour.
Therefore, Sue will bike at a speed of 25 miles per hour next week.
