Anna drives her car at a speed of 70 km per hour. How much distance will she cover in 3 hours 30 minutes?

Tresset [83]

Answer:

$\sf \: 245 km$

Step-by-step explanation:

$\sf Speed \: of \: the \: car = 70 km/h$

$\sf Time \: taken = 3 \: hours \: 30 \: minutes$

$= \sf 3 \frac{1}{2} \: hours$

$\sf = \frac{7}{2} \: hours$

$\sf Distance = Speed \times Time$

$\sf Distance = 70 \times \frac{7}{2} \: km$

$\sf Distance = 245 \: km$

Hence, Anna will cover 245 km in 3 hours 30 mins.

Question 3

wariber [46]

Answer:

Incorrect

The correct answer is 1/6

Step-by-step explanation:

Freddy is incorrect. You are not supposed to subract the denominators. When you are solving the equation you have to find a common denominator. You can only subtract the numerator, and the denominator is the same.

Find the LCM. The LCM in this case is 6.

$\frac{3}{6} -\frac{2}{6}$

Remember, only subtract the numerators. The denominator will still be 6.

$\frac{1}{6}$

1/6 is the correct answer. I hope this helps you!
