Problema Solution
two families who lived 63 miles apart met at a park between their homes for a picnic. how long did each drive if both travelled at a rate of 45 miles an hour and one drove 12 minut
Answer provided by our tutors
v1 = 45 mph
v2 = 45 mph
t1 = 12 min = 12/60 hr = 1/5 hr = 0.2 hr
t2 = ?
d = 63 mi
Since distance=rate*time we have:
v1t1 + v2t2 = d
45*0.2 + 45t2 = 63

........
t2 = 1.2 hr
t2 = 1 hr 0.2*60 min
t2 = 1 hr 12 min
The other family drove for 1 hour and 12 minutes.
