Explanation:
It is given that,
Power consumed by toaster oven, 
Time taken, t = 6 minutes = 0.1 hour
Energy used by toaster, 

Similarly,
Power consumed by toaster oven, 
Time taken, t = 9 minutes = 0.15 hour
Energy used by toaster, 

Hence, this is the required solution.
R=U/I so
U=RxI
U= 10 x 42
U= 420 volts
Answer:
The car will travel 30 miles during the 30-minutes period of acceleration.
Explanation:
Given data :
Initial velocity = v₁ = 50 miles/hour
Final velocity = v₂ = 70 miles/hour
Time = t = 30 min = 0.5 hour
Using the definition of acceleration, we find the acceleration (a)
a = (v₂ - v₁) ÷ t
a = (70 - 50) ÷ 0.5
a = 20 ÷ 0.5
a = 40 miles/hour²
Using 3rd equation of motion, we find the distance travel (s)
2as = v₂² - v₁²
2(40)s = 70² - 50²
80 × s = 4900 - 2500
s = 2400 ÷ 80
s = 30 miles
