You're given the value of m so you plug that in the equation given to get 1500=-475t+2650. Now with some algebra just solve it for t! so subtract 2650 and get -1150=-475t. Now divide by -475 and get 2.4. Now the t value is already in hours, so there's no conversions, and the closest answer is A! This makes sense because it's an approximation :)

Answer:
5mph
Step-by-step explanation:
Given that two cars are 40 miles apart at the beginning.
They started at the same time with speeds 48 mph and 56 mph respectively
Since both cars are travelling in the same direction,
Relative velocity = Speed of the behind car-Speed of the first car
=56-48 =8mph
To catch the I car, the second car has to travel a distance of 40 miles extra in the same time as the I car
i.e. speed to be made up by the second car = 40 miles
Relative velocity per hour = 8mph
Hence time taken to catch up =
