Question

Help please I’m Confused He and she are competing in a 42 mile race. He has already finished 18 miles of the race and is traveling at a constant speed of 12 miles per hour. She starts at 16 miles per hour. Equation: 18+12x= 0+ 16x (x= 4.5 hrs) at what constant speed could Wanda travel to catch up with Hector at the finish line

Answer 1

Hector : 42-18=24
H = 12(2) because 12 x 2 = 24

24divide16=1.5
W=16(1.5) because 16 x 1.5 = 24
