Distance and time.
Miles per hour and seconds are units of measurement of speed and time respectively, which are scalar quantities.
Meters per second squared, Kilometers per hour, Meters, and Miles per hour.
'Velocity' should be compared with 'speed', and it should be understood that they're different. "30 miles per hour" is a speed. "30 miles per hour toward the south" is a velocity.
A rate is a ratio of two quantities: miles per hour, calories per cookie, dollars per person, ... a unit rate just specifies the units (miles, hours) of the two quantities.
Grams and seconds.
A ratio that compares two quantities measured in different units is known as a "rate." Rates express the relationship between the two quantities, allowing for comparison despite their differing units. For example, speed is a rate that compares distance (measured in miles or kilometers) to time (measured in hours), such as miles per hour (mph) or kilometers per hour (km/h). Rates provide a standardized way to understand how one quantity relates to another across various contexts.
distance in miles and time in hours. both are scalers.
50 miles per hour.
About 55 miles per hour.
40 kilometers per hour = 24.85 miles per hour.
1,200 (kilometers per hour) = 745.645431 miles per hour.
35 miles per hour = 56.32704 kilometers per hour
