Answer: 128.7 inches
Step-by-step explanation:
Josh's height is 66 inches.
When he jumps with a running start, he can jump as far as 195% of his height.
The length he can jump is therefore 195% multiplied by his height:
= Josh height * 195%
= 66 * 195/100
= 128.7 inches
Answer:
432
Step-by-step explanation:
Okay so george and his dad plant 18 to a row and 3 rows an hour. So thats 3 rows of 18 an hour.
So first: Multiply 18 x 3 to find out how many trees they plant each hour.
18 x 3 = 54: So they plant a total of 54 plants each hour.
Next: to find out how many they planted in 8 hours multiply 54 plants x 8 hours
54 x 8 = 432 trees per 8 hours
Hope it helps :P
Wow ! Let's see now . . .
Let's say the passenger train takes ' P ' hours for the trip.
Then the freight train takes ' P + 1.5 ' hours for the same distance.
The speed of the passenger train is 60, so he covers ' 60P ' miles.
The speed of the freight train is 40, to he covers ' 40(p+1.5) ' miles.
But the distances are equal !
60P = 40(P + 1.5) . . . . . There's your equation !
Eliminate parentheses on the right side:
60P = 40P + 60
Subtract 40P from each side:
20P = 60
Divide each side by 20 :
P = 3
The passenger train takes <u>3 hours</u>, and the
freight train takes (P+1.5) = <u>4.5 hours</u>.
Check:
In 3 hours, the passenger train covers (3 x 60) = 180 miles .
In 4.5 hours, the freight train covers (4.5 x 40) = 180 miles .
It works.
yay !
