Using the formula r=d/t where d is the distance in miles, r is the rate and t is the time in hours at which rate must you travel to cover 337.5 miles in 4.5 hours? a-55mph

b-65mph

c-75mph

d-85mph

the answer is c-75mph

337.5 is the distance (d) and 4.5 is the time (t)

to find r it is d/t, so 337.5÷4.5 is 75mph so the answer is c

to find r it is d/t, so 337.5÷4.5 is 75mph so the answer is c

A child puts one five-rupee coin of her saving in the piggy bank on the first day. She increases her saving by one five-rupee coin daily. If the piggy bank can hold 190 coins of five rupees in all, find the number of days she can continue to put the five-rupee coins into it and find the total money she saved.

1 day => 1 coin

190 days => 190 coins (full)

so it takes 190-1=189 more days to fill it

total money saved = 190x5=950 rupees
