It took amir 2 hours to hike 5 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 1.5 mile per hour. which equation can be used to find t, the amount of time amir spent hiking during the second, more difficult part of the hike?

The formula to find time spent hiking during the second part of hike was derived from the basic formula of average speed which is the total number of speed during both parts of hike equals to the total distance traveled divided by total time taken. 

is there answer choices?

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
