Given :
Michaela runs to the end of her street and back in 90 s.
Her brother, Jacob, walks to the end of the street and back in 3 min.
They both run or walk for the same amount of time, but Michaela makes 5 more trips than Jacob.
To Find :
How many times did each person go to the end of the street and back.
Solution :
Let, they both walk for T seconds.
Number of rounds Michaela walk is, n₁ = T/90 .
Number of rounds Jacob walk is, n₂ =T/180 .
It is given that :
n₁ = n₂ + 5
T/90 + T/180 = 5
( T/90 + T/180 ) × 180 = 5×180
2T + T = 900
3T = 900
T = 300 s
So, n₁ = 300/90 = 3
n₂ = 1
Hence, this is the required solution.
(5/8) * (4/7) + 45 * .05 = 2.60714285714

Answer:
17.55 tubs
Step-by-step explanation:
step 1
Find out the total scoops of ice cream in 234 regular cones and 156 large cones
step 2
Find out the weight of the total scoops
we know that
One scoop of ice cream is 3 ounces
so
step 3
Convert ounces to pounds
Remember that
1 pound = 16 ounces
so
To convert ounces to pounds divide by 16
step 4
Find out how many ice cream tubs Richard used to make the cones
we know that
A tub of ice cream weighs 10 pounds
Divide the total weight in pounds by 10
804 * 219 = 176,076
3674 * 89 = 326,986
4321 * 96 = 414,816
6782 divided by 5 = 1356.4
3224 divided by 96 = 33.58
3224 divided by 8 = 403
