Question 1035481: Please help me I never been good with word problems. Thanks
The radius of a hailstorm varies directly with the amount of time that it was in a cloud. After a hailstorm had been in a particular cloud for 10 seconds, its radius for 0.5 inches. How long would it have to be in the cloud to have a radius of 1.25 inches.

Hi there,
The radius of a hailstorm varies directly
with the amount of time that it was in a cloud.
Radius = k x Time (in cloud)
k is the constant of proportionality.
R = k x T
0.5 = k x 10
k = 0.5/10
k = 0.05
Formula:
R = 0.05 x T
........
1.25 = 0.05 x T
Time = 1.25/0.05
Time = 25 seconds.
Hope this helps :-)
