Question

HELP QUICK IM GIVING 21 POINTS AND A BRAINLIEST AWARD

Answer 1

Answer:

10:45

Step-by-step explanation:

v...speed = 40 mph

s...distance = 60

t...time

if he was 15 min late he arrived at 12:15

v=s/t => t=s/v

t = 60/40 = 1.5 h = 1h and 30 min

if he arrived at 12:15 and he was driving for an hour and a half just substract

12:15 - 1:30 = 11:15 - 0:30 = 10:45

he left at 10 45

Answer 2

V...speed = 40 mph
s...distance = 60
t...time

if he was 15 min late he arrived at 12:15

v=s/t => t=s/v
t = 60/40 = 1.5 h = 1h and 30 min

if he arrived at 12:15 and he was driving for an hour and a half just substract
12:15 - 1:30 = 11:15 - 0:30 = 10:45

he left at 10 45
