4. A car travels 120 miles in the same amount of time that it takes a truck to travel 100 miles. The car travels 10 miles per hour faster than the truck. Find the speed of the truck

The speed of the truck is 1,200 miles.

Step-by-step explanation:

Car = 10 MILES PER HOUT FASTER THAN THE TRUCK.

Truck = X times 10

X = 120 MILES times 10

120 times 10= 1,200, BECAUSE IF YOU TAKE THE "1" FROM "10" IT'LL BE "1" FROM THE 10, TIMES 120 MILES WHICH = 120. NOW TAKE THE "0" FROM THE 10 AND ADD *0* AT THE END OF THE ANSWER YOU GOT WHICH WAS "120." THEN YOUR ANSWER WILL BE 1,200 IF YOU ADD THE "0" AT THE END.
