In my number, the digit in the ones plase is double the digit in the place. The sum of the digits is 3

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
