If Monica walks
1km...........................15min
?km............................60min
60/15=4
Monica walks 4km in 60 min(1H)
1km=1,000m
4km=4,000m in 1 hour
Answer:
0.5hrs
Step-by-step explanation:
Let the speed downhill be 
,
Speed uphill is 
. We are told than speed uphill is 
the speed on flat ground. Therefore the speed on level ground will be 
.
From this info, we can obtain the actual speed,
on level ground as:
speed, distance and time have the relation 
so to obtain time to cover 45miles:
Hence it takes 0.5hrs to cover 45miles on flat ground.
Answer:
W > 0.5L
Perimeter:
2L + 2W < 180
2L + 2(0.5L) < 180
2L + 1L < 180
3L < 180
÷3 ÷3
L < 60
Length should be less than or equal to 60 inches while width should be greater than or equal to 30 inches.
Answer:
lets call the children, c, and call adult, a,
c+a= 52 eq 1: a=52-c
c=3a eq 2
take a's value from eq 1 and plug it into eq 2
c=3(52-c)
c=156-3c
4c=156
c=39 the number of children that attended the ball game.
