Question

shawns engineering club is taking a trip by bus to a robotics fair. the fair is 175 miles from shawns school. the bus driver plans to stop and refuel after 2 hours, then complete the trip. the bus driver plans to drive at an average speed of 50 miles per hour. how many hours will the second - part of the trip take? write your answer as a whole number or a decimal.

Explanation:

Step1: Calculate distance in 2 hours

$d_1 = 50\times2=100$ miles

Step2: Calculate remaining distance

$d_2=175 - 100 = 75$ miles

Step3: Calculate time for second - part

$t=\frac{d_2}{v}=\frac{75}{50}=1.5$ hours

Answer:

2.5
