### Explanatory Answer | GMAT Average Speed

#### Step 1: Compute Total Distance Travelled

Average speed of travel = $$frac{\text{Total distance travelled}}{\text{Total time taken}}$ Total distance traveled by Steve = Distance covered in the first 2 hours + distance covered in the next 3 hours. Distance covered in the first 2 hours = speed × time = 40 × 2 = 80 miles. Distance covered in the next 3 hours = speed × time = 80 × 3 = 240 miles. Therefore, total distance covered = 80 + 240 = 320 miles. #### Step 2: Compute Average Speed Total time taken = 2 + 3 = 5 hours. Total distance travelled = 320 miles. Hence, average speed = $\frac{\text{Total distance travelled}}{\text{Total time taken}} = \frac{320}{5}$ = 64 miles per hour. #### Choice D is the correct answer. #### GMAT Online CourseTry it free!
