Can you solve this problem?

Question

The distance traveled by a 75 mph train in 2 hours is 150 miles.
Compare each question with the information above.
a) Begining at a standstill, a car maintains a constant acceleration of 10 ft/sec^2 for 10seconds. What is its velocity after 10seconds? Give your answer in ft/sec and then convert in to mi/h.
b) In a vacuum, light travels at a speed of 300,000 kilometers per second. How many kilometers does it travel in a year? (This distance equals one light-year.)
c) A long distance runner ran in 5 hours, avering 6 mph for the first 3 hours and 5 mph for the last 2 hours. How far did she run?
This is a calculus problem. Please explain the answer in detail if you can.
This is a calculus problem.

Answer 1

comparing each question to the information which was given:

a) the train is faster than the car
b) the speed of light is faster than the train
c) the train is faster than the runner

c) linear equation is not calculus
(6 x 3) + (2 x 5) = answer in 5 hours travellled
