Shannon test-drives a car in Germany and drives 95 kilometer per hour. What is her speed in miles per hour? (1 kilometer < 0.
victus00 [196]

Answer:

58.9 miles per hour

Step-by-step explanation:

Step 1: Convert 95 Kilometers per hour to miles per hour

1 Kilometer = 0.62 miles

95 Km x \frac{0.62 miles}{1 km}

cancel Km

95 Km x \frac{0.62 miles}{1 km}  = \frac{95}{1} x \frac{0.62 miles}{1} = \frac{58.9 miles}{1} or 58.9 miles

Change it into speed

58.9 miles per hour (59 miles per hour (Round off))

(Note: I don't know if I should round off because the instructions aren't that clear. This solution might or might not have been thought to you by your lecturer.)

Allison is rolling her hula hoop on the playground. The radius of her hula hoop is 35 \text{ cm}35 cm35, start text, space, c, m
scoray [572]

Answer: 880 cm

Step-by-step explanation:

Given: Radius of the hula hoop = 35 cm

Hula hoop is  circular in shape

Then, Circumference = 2\pi r , where r = radius

Now , Circumference of hula hoop = 2\times \dfrac{22}{7}\times35=220\  cm

Now , the distance the hula hoop rolls in 4 full rotations = 4 × (Circumference of hula hoop)

= 4 \times 220=880\ cm

Hence, the required distance = 880 cm
