Question

A probe is traveling to mercury is 4.8 x 10^7 miles away the probe travels at a rate of 6 x 10^4 miles per hour. Using the formula: time = distance / rate determine how long it would take the probe to reach mercury all units are in hours.

A. 0.8
B. 2.88 x 10^4
C. 8 x 10^2
D. 1.2 x 10^3

Please help

Answer 1

it's c.8*10^2.
time=distance/rate
time=4.8*10^7/6*10^4
time=0.8*10^3
time=8*10^2
