Question

Jesse rode his bike for 2 hours at a constant rate. During the first 1.5 hours, he rode 15 miles. How many miles did jesse ride his bike during the last half hour? (enter an exact number.)

Answer 1

Jesse rode his bike 5 miles during the last half hour.

Step-by-step explanation

Suppose, the constant speed of the bike is
`x` miles/hour

Jesse traveled 15 miles for the first 1.5 hours. As
`Speed= (Distance)/(Time)` , so the speed of the bike will be:
`(15)/(1.5) =10` miles/hour

Now also,
`Distance= speed*time`

So, the distance traveled for the last
`(1)/(2)` hour will be:
`10*(1)/(2)= 5 miles`
