1.
Formula
s=d÷t
where:
d is the distance
t is the time
s is the speed
186.15 ÷3= 62.05
speed=62.05kph (kilometers per hour)
2.
387.60÷4= 96.9
96.9 each student organization
3.
105÷6= 17.5
17. 5 is the cost of one apple
70÷8= 8.75
8.75 is the cost of one orange
So ;
(2×17.5)+(3×8.75)=N
35+26.5=N
=61.25 is the total cost
100-61.25=38.75
the change is 38.75
4.
50 ÷ 0.5 or 2 or 1/2
25×5=125
125.00 is Albert's savings for 5 days
5.
15m=150 dm
150dm÷2.4dm=62.5
