Answer:
Cheapest cost to pay = £906
Step-by-step explanation:
Given that:
Rice to supply = 50 tonnes
Option A:
Big van has capacity of 15 tonnes.
Number of big vans = 
It means that 4 big vans will be needed for transporting 50 tonnes of rice.
Cost of 4 vans = 4*250 = £1000
Option B:
Small van has capacity of 9 tonnes.
Number of small vans = 
It means that 6 small vans will be nedded for transporting 50 tonnes of rice.
Cost of 6 vans = 6*151 = £906
Therefore,
The company can transport the rice through small vans.
Hence,
Cheapest cost to pay = £906
Answer:
2 bowls of soup
Step-by-step explanation:
<u>1. Make 1 1/4 an improper fraction</u>
1 1/4 = 5/4
<u>2. Then divide 5/4 by 5/8 (KCF - </u><u>Keep</u><u> the 5/4 - </u><u>Change</u><u> the division sign to multiplication - '</u><u>Flip' </u><u>5/8 to 8/5)</u>
5/4 x 8/5 = 40/20
<u>3. Simplify the fraction (divide the numerator and denominator by 20)</u>
40/20 = 2
<u>4. Final answer:</u>
2 (bowls of soup)
Last answer. 288. Modifying above 8 with bar
Time = Distance / speed
Let X = number of hours.
Car 1 is driving 30 miles per hour for X hours, so you have 30x.
Car 2 is driving 40 miles per hour for x hours, so you have 40x.
30x +40x = 70x
70x = 350 miles
x = 350 / 70
x = 5
They will meet in 5 hours
