Answer:
The answer to your question is 2 hours
Step-by-step explanation:
Data
Juan speed = 4 mi/h
Cathy speed = 7 mi/h
t = x
Formula
speed = distance/time
Solve for distance
distance = speed x time
d = s x t
Distance travelled by Juan
d = 4t
Distance travelled by Juan in 1.5 h
d = 4(1.5)
d = 6 mi
total distance d = 6 + 4t
Distance travelled by Cathy
d = vt
d = 7t
Equal both equations
6 + 4t = 7t
Solve for t
6 = 7t - 4t
6 = 3t
6/3 = t
2 = t
Cathy wll catch up with Juan in 2 hours
Answer:
2.5
Step-by-step explanation:
8 -48 = 3 +13
*ADD 48 from each side(so -48+48=0 and 13+48=61)
8 = 3 +61
*Subtract from each side(so 3-3=0 and 8-3=5)
5 = 61
*Now u divide 5/5=1 and 61/5=2.5
