group A hikes 2.4 miles per hour. Group B hikes 2,8 miles per hour when A hikes 9 miles how many miles has B hiked?
To find out how many miles group B has hiked, we first need to determine how long group A has been hiking.
We can use the formula: Time = Distance / Speed
Let's calculate the time taken by group A to hike 9 miles:
Time A = Distance A / Speed A
Time A = 9 miles / 2.4 miles per hour
Time A ≈ 3.75 hours
Now, we can use the time taken by group A and group B's speed to find out how many miles group B has hiked.
Distance B = Speed B * Time A
Distance B = 2.8 miles per hour * 3.75 hours
Distance B ≈ 10.5 miles
Therefore, when group A hikes 9 miles, group B has hiked approximately 10.5 miles.
