Answer:
5 hours
Step-by-step explanation:
subtract 390 by 215 to get 175 then divide 175/35 to get 5
The reaction times form a straight line with gradient of 60/140 = 3/7 m/kph
Reaction time at 130 kph = 3/7 x 130 = 390/7 = 56 m to nearest whole number
Answer:
C. 25 ÷ 10
Step-by-step explanation:
A. 10/25
B. 2/5
C. 25 ÷ 10
D. 0.4
Total customers at Becky's restaurant = 25
Customers who order wheat rolls = 10
It means 10 out of 25 customers order wheat rolls
That is
10 / 25
Dividing both numerator and denominator by 5
= 2 / 5
2/5 in decimal
= 0.4
The option Which does NOT represent the part of the customers who order wheat rolls
is 25/10
Option C. 25 ÷ 10
168/6 = 28
Tim can solve 28 problems in one minute.
C. 21/45
If you multiply both the 7 and 15 by 3, you get 21 and 45.
