Question

It took Amir 1.75 hours to hike 5.1 miles. On the first part of the hike, Amir averaged 3 miles per hour. For the second part of the hike, the terrain was more difficult so his average speed decreased to 2.4 miles per hour. What equation can be used to solve for t, the amount of time Amir spent hiking during the second, more difficult part of the hike?

a. 3(1.75 – t) = 2.4t
b. 3t = 2.4(1.75 – t)
c. 3t + 2.4(1.75 – t) = 5.1
d. 3(1.75 – t) + 2.4t = 5.1
