Answer:
t = 11.3 hours
Step-by-step explanation:
The formula d = rt stands for distance = rate x time. The problem gives you the rate, or r = 48.3 m/h, and the distance, or d = 545.79m. To solve for 't', you can plug the values given and divide:
d = rt or 545.79 = 48.3(t)
Divide both sides by 48.3: 545.79/48.3 = 48.3t/48.3
Solve for t: t = 11.3 hours
Answer:OB. 10cups of flour and 6 cup of sugar
Step-by-step explanation:
1/3 of x + 1/5 of x = 16
x/3 + x/5 = 16
5x + 3x / 15 = 16
8x/15 = 16
8x= 15×16
8x = 240
x= 30
1/3 of flour
1/3 × 30
=30/3
=10
flour = 10cups
1/5 of sugar
1/5 × 30
=30/5
=6
Sugar = 6 cups
10cups of flour and 6 cups of sugar
