Question

A Walmart truck driver estimates that it will take him 12 hours to drive 1152 km. After 5 hours, he has driven 520 km.

(a) According to his original estimate, how far would he drive in 1 hour? Show your number sentence and solution.

(b)Is he on schedule to arrive on time? Use a UNIT RATE to explain your reasoning.

Answer 1

(a) He would drive 96 km in an hour because 1152 divided by 12 is 96

(b) He is technically on schedule because he is driving 104 km per hour, instead of 96, so if he keeps driving at the same rate, he should get there in under 12 hours
