16. A truck traveling 45 miles per hour and a train traveling 60 miles per hour cover the same distance. The truck travels 2 hou
Snowcat [4.5K]

Answer:

A.

Step-by-step explanation:

d = rt

If t is the time taken by the train, then the truck takes t+2 hours.

For the truck:

d = 45(t + 2)

For the train:

d =  60t

Total distance travelled by both:

= 2d

= 60t + 45(t + 2)

= 60t + 45t + 90

= 105t + 90      where t is the time taken by the train.
